Robotic Cow Milking

The Washington Post has an article
on the growing field of dairy robotics. The newest cow
milking robots need almost no human assistance and rely on voluntary
participation from the cows. Just reading the company web pages will
provide some entertainment. Lely calls their product the
Astronaut
Milking Robot while DeLaval's
web site claims they're able to build "cow-friendly" robots because they
understand "cow psychology". The Robotic Milking Industry even has its
own web site to promote use
of milking robots.
